The study, which was led by Jonathan I. Silverberg, M.D., Ph.D., M.P.H., of St. Luke's Roosevelt Hospital Center, New York, and colleagues, involved analyzing data gathered from a questionnaire in the 2007-2008 National Survey of Children's Health, which included a total of 91,642 children 0 to 17 years old...

Dust In Air Of Underground Railways May Harm Health

Date: Apr-30-2013
A new UK study suggests that microscopic dust particles in the air of underground railways may pose a risk to health for people who spend sustained periods of time in that environment, such as railway workers and city commuters. Matt Loxham, a doctoral student at the University of Southampton, and colleagues, report the results of their investigation of a European underground station in Environmental Science and Technology...

New Studies Prove Lethal Link Between Alcohol, Weight And Liver Disease In Women

Date: Apr-30-2013
Research announced last week at the International Liver CongressTM 2013 has revealed the deadly impact that alcohol and body weight have on liver disease. Women should forgo the wine and doughnuts after a new study found the harmful combination of high alcohol intake and high body mass index (BMI) causes an increased risk of chronic liver disease. The study analysed a cohort of over 107,000 women to investigate how a female's weight and alcohol consumption affected their chances of suffering and dying from chronic liver disease.1 EASL's Scientific Committee Member Dr...

Dark Field Imaging Of Rattle-Type Silica Nanorattles Coated Gold Nanoparticles In Vitro And In Vivo

Date: Apr-30-2013
In recent years, metal nanoparticles have showed great application prospect in the field of biological imaging, cancer diagnosis and treatment due to its unique optical scattering and optical absorption properties. In many metal materials, gold nanoparticles have caused concerns in the field because of its simple preparation, easy to modify advantages. However, the poor stability in physiological fluids environment and the potential toxicity of gold nanoparticles always restricts its application in the biological field...

National Expenditures On Emergency Care Are Likely Significantly Higher Than Previously Thought

Date: Apr-30-2013
U.S. emergency care costs may be more than twice previously published estimates, according to a new analysis that critiques those estimates, argues for improved accounting, and suggests considering the value of emergency care as well as total spending. Alternately praised in the aftermath of horrible tragedies as a heroic service and lamented in policy debates as an expensive safety net for people without primary care, emergency medicine is often a hot topic...

Immune Cells Taught By Thymus To Ignore Vital Gut Bacteria

Date: Apr-30-2013
The tiny thymus teaches the immune system to ignore the teeming, foreign bacteria in the gut that helps you digest and absorb food, researchers say. When immune cells recognize essential gut bacteria as foreign, inflammatory bowel disease such as ulcerative colitis and Crohn's disease can be the painful, debilitating result. In a study published in the journal Nature, researchers show that the regulatory T cells, or Tregs, that keep this from happening in most of us come from the tiny immune organ nestled near the heart, said Dr...

Warning System Predicts Outbreaks Of Dengue Fever

Date: Apr-30-2013
With the help of a warning system which measures the risk of dengue incidence using precipitation and air temperature, it is possible to forecast the outbreak of dengue fever up to 16 weeks in advance. This is what Yien Ling Hii concludes in the dissertation she is defending at Umea University on 3 May. Dengue fever is an infectious disease caused by virus and transmitted to persons by mosquitoes. A person contracted dengue fever usually shows symptoms including sudden spike of high fever, muscle ache, joint pain, rashes, and headache...

The Dual Role Of Testosterone In Schizophrenia

Date: Apr-30-2013
Researchers from Neuroscience Research Australia (NeuRA) have presented new results about the role of testosterone in schizophrenia at the International Congress on Schizophrenia Research being held in Orlando, Florida. They have found that, on the one hand, testosterone could be the trigger for the onset of schizophrenia. On the other, increased testosterone levels are associated with increased cognitive abilities of men with schizophrenia...

A New Approach To Treating Trauma

Date: Apr-30-2013
Queensland medical experts are spearheading a new trauma care model they say will improve patient care from the roadside to recovery. The multi-disciplinary team has adopted a new model in which researchers work side-by-side with paramedics, medical staff, allied health professionals and rehabilitation specialists. Heading the Integrated Trauma Centre is orthopaedic surgeon Professor Michael Schuetz, Chair of Trauma at QUT's Institute of Health and Biomedical Innovation (IHBI) and Director of Trauma at Brisbane's Princess Alexandra Hospital (PAH)...

Cardio Could Hold Key To Cancer Cure

Date: Apr-30-2013
Regular exercise has been proven to reduce the chance of developing liver cancer in a world-first mice study that carries hope for patients at risk from hepatocellular carcinoma (HCC). The research announced at the International Liver Congress(TM) 2013 involved two groups of mice fed a control diet and a high fat diet then divided into separate exercise and sedentary groups.[1] The exercise groups ran on a motorised treadmill for 60 minutes per day, five days a week...
